ADG636

1 pC Charge Injection, 100 pA Leakage, CMOS, ±5 V/+5 V/+3 V Dual SPDT Switch

Manufactured by:

Product Details

The ADG636 is a monolithic device, comprising two indepen-dently selectable CMOS single pole, double throw (SPDT) switches. When on, each switch conducts equally well in both directions.

The ADG636 operates from a dual ±2.7 V to ±5.5 V supply, or from a single supply of +2.7 V to +5.5 V.

This switch offers ultralow charge injection of ±1.5 pC over the entire signal range and leakage current of 10 pA typical at 25°C. In addition, it offers on resistance of 85 Ω typical, which is matched to within 2 Ω between channels. The ADG636 also has low power dissipation yet is capable of high switching speeds.

The ADG636 exhibits break-before-make switching action and is available in a 14-lead TSSOP package.

EVAL-14TSSOPEBZ

EVAL-14TSSOPEBZ Circuit Diagram

Product Details

The EVAL-14TSSOPEBZ evaluation board evaluates 14-lead TSSOP devices in the Switches and Multiplexers Portfolio that must be purchased separately from the evaluation board. A clamp is supplied with the EVAL-14TSSOPEBZ to secure a 14-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.

A 14-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device that the eval board evaluates has a corresponding link from K1 to K14 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.

For full details, see the corresponding product data sheet, which must be used in conjunction with this user guide when using the evaluation board.
